3 Claims.

the forms illustrated in the accompanying draw ing, attention beingcalled to the fact, however, that the drawing is illustrative only, andthat. change may be made in the specific constructions illustrated anddescribed, so long as the scope of the appended claims is not violated.

Fig. 1 is a fragmental perspective view of the lower portion of a door;

Fig. 2 is an end elevation of a door and threshold, as viewed from theright of Fig. 1;

Fig. 3 is a sectional view taken substantially on the line 3--3 of Fig.3 and looking in the direction of the arrows;

Fig. 4 is a transverse section taken in a plane perpendicular to theplane of Fig. 3; and

Fig. 5 is a view similar to Fig. 4, but showing a modified form of theinvention.

Referring more particularly to Figs. 1 to 4 inclusive, it will be seenthat I have illustrated a door In surrounded by the usual frame elementscomprising a floor II, an upright I2 adjacent the free edge of the door,and an upright I3 adja cent the hinged edge of the door. I haveillustrated the door as provided with the usual weather-excludingthreshold I4, normally provided with outside doors; but it is to beunderstood that such a threshold member I4 is not an essential of myinvention, and that a floor which closely underlies the lower edge ofthe door may be, in all particulars, the equivalent of such a thresholdmember.

The door It! is hinged as at I5 to swing outward- 1y, as viewed in Fig.1.

Along its lower edge, the door III is formed with an elongated recessI6, the longitudinal extent of which is substantially equal to thelateral width of the door I0. At each lateral edge of the door there isprovided a bracket member I'I, set flush with the edge, of the door, andprovided with a boss I8 facing inwardly, each boss I8 being formed witha cylindrical socket I9.

In the sockets I9 are journaled the trunnions i 20, one being formed ateach end of a strip 2I hich is preferably made of cast metal.

The trunnion's 20 are formedin line with one longitudinal edge ofthestrip 2!, whereby the opposite edge 22 of said strip is free to swingas the strip oscillates about the axes of the trunnions 2B;

At thefree edge 22, the stripis formed with a beveled surface 23 whichleads to a groove 24 in which is received a strip of rubber, or other;

compressible material 25. The portion 26 of the strip 2i is cut back, asis clearly shown in Figs; 2 and 4.

That edge of the strip 2|. on which the trunnions 20 are formed ispreferably formed as a radiused surface 21 centered on the axes of thetrunnions, for a reason later to be brought out.

The strip 2| is formed, on its upper surface, With a lug 28 perforatedfor the reception of one end of a spring 29, the oppositeend of which isanchored on a screw 30 seated in the upper Wall of a suitably formedrecess 36. The lug 28 is preferably formed substantially midway betweenSaid strip 32 has a sealing engagement with the radiused surface 2? ofthe strip 2I whereby, as said strip 2I oscillates about the axes of thetrunnions 20, a sealing engagement is constantly maintained withoutvarying the degree of compression of the strip 32. Of course, thepurpose of the strip 32 is to seal'the space between the weathe er strip2! and the upper wall of the recess lii against air flow through saidrecess from one side of the door tothe other. a

At a suitable point in its length, preferably adjacent one end thereof,the strip H is provided even in the position illustratedin' Fig. 4,pro.- jects slightly from the recess I6. 'Whenthe door II) is moved toclosed position, the'lug 33 engages an abutment member .34 carried upona plate 35'set flush in the threshold I4, said abut- I ment member 34projecting, of course, above the surface of the threshold I4 and intothe path of the lug 33. I

It Will be entirely clear that, as the door I0 is 45 with a downwardlyprojecting lug' 33 which,

shown in Fig, 2, the spring 29 will tend to rotate the strip 2i inacounterclookwise direction about the axes of the lugs 20,,such rotationbeing resisted only by the engagement of the lugv 33 against theabutment member 34., As the door begins to move in an opening direction,the strip 2i will be so rotated until, as the lug 33 leaves the abutmentmember 3%, the strip 2i will have assumed the position illustrated'inFig. l. Now, when the door is again moved, toward closed position, theprojecting portion of the lug 33 will engage the abutment member 34 justbefore complete closure is efiected; and as the door H) is brought toits final position, the edge 22 'of the strip 2i will be thrown downinto .the position illustrated in Fig. 2. As the strip M is so swung, ofcourse the leading corner or" the compressiblestrip 25 will first engagethe threshold; and completion of the door-closing movement will compressand deform that corner of the stri 25 so that a true sealing engagementbetween the strip 25' and the threshold Hi will be effected.

The embodiment of Fig. 5 is quite similar. A.

door 3? is formed with a recess 38 similar to the recess I 6, and ametal strip 39 is suitably mounted in said recess. The free'edge of thestrip 39 is formed with a socket 3B for; the reception of a strip 4! ofrubber, or other compressible material. Said stripBQ is alsoprovided-with a lug $2 in which isengaged one end of a springjlBsuitably anchored in the door and tending to lift the free edge of thestrip 39into the socket 33.

A socket t l formed in the door rec-eivesa strip of very highlycompressible material which engages'constantly against the upper surfaceof thestrip 38, said material 45 being deformable,

as the strip 39 is moved into the recess 38 under the effect of thespring fl, e

A lug 45 on the strip 39 cooperates with a lug 41 set into thethreshold, the cooperative eifect moved toward open position from theposition of saidftwo lugs being identical with the efiect of the lugs 33and 34.

I claim as my invention:

1. In combination with a swinging closure, means forsealing the spacebetween an edge of said closure and its frame comprising an elementhingedly mounted within said closure, means automatically operable, whensaid closure is moved to closed position, to rotate said element intointimate contact with said frame. and a strip of soft rubber, or thelike'sealed in said closure and engaging a portion of said elementconcen trio with the hinge-axis thereof substantially throughout thelength of said element.

2.'The combination with a closure having a recessformed in its loweredge and having a substantially entirely within said recess, meansoperable upon movement of said closure to swing said weather strip outof said recess andjinto intimate contact with the frame of said closure,

and a strip of compressible material sealed in said closure withinsaidrecess and having a sealing engagement with said radiused surface.3. The combination with a closure having a recess formedin its loweredge and having a longitudinal extent" substantially equal to the widthof the closure, of a Weatherstrip oscillably mounted in said recess,spring means: resiliently holding said stripsub'stantially entirelywithin said recess, means operable upon movement of said closure toswing saidfweather strip out :of said recess and into intimate contactwith the material sealed in said closure within said recess andconstantly maintaining a sealing engagement with an upper surface ofsaid weather strip.
